Solvent-based gravure printing ink for lamination, printed material and laminate

Abstract

A solvent-type gravure ink for a laminate according to the present invention contains a pigment, a binder resin, an organic solvent, and water. The solvent-type gravure ink contains 80 to 100 mass % in total of a polyurethane resin and a vinyl chloride copolymer resin in 100 mass % of the binder resin, and the mass ratio of polyurethane resin to vinyl chloride copolymer resin is 95:5 to 40:60. The solvent-type gravure ink contains 1 to 50 mass % of a structural unit derived from a polyether in 100 mass % of the polyurethane resin. The solvent-type gravure ink contains 0.1 to 15 mass % of a glycol ether-based organic solvent serving as the organic solvent and 0.1 to 5 mass % of the water in 100 mass % of the gravure ink.
